Our SafeTCap ART-131-4-R repairs the TJ full center frame from the front body mount to approximately 1 inch before the rear coil spring plate. The frame cap is made from 11 gage cold rolled steel and has four new transmission skid plate weld nuts for remounting the skid plate after the frame kit is installed. Factory welded to the ART-131-4 frame component are the upper and lower trailing arm mounts and the rear axle sway bar mount bracket. The upper and lower trailing arm mounts are made from 7 gage hot rolled steel, and the sway bar mount is made from 11 gage cold rolled steel. The sway bar mount and the upper trailing arm mount have factory installed weld nuts.
Each ART-131-4 SafeTCap frame repair kit comes with new high grade skid plate and trailing arm mounting hardware, and detailed step-by-step instructions.
The ART-131-4-R is designed to fit the passenger side. This part will not fit the LJ models.
